The histopathological finding that in brain tissues of NiV-infected patients, syncytial cells were only found in 27% of the cases whereas vasculitis, thrombosis and necrosis were seen in over 80% [13] might reflect differences in the EB2 expression levels resulting in different extents of NiV-mediated cell-to-cell fusion. This evidence concerns the gene MAPRE2 and vasculitis.
